Key legal question
Whether the appeal against the cantonal remand order was admissible under Art. 93 BGG
Extracted holding
The remand order was an interlocutory decision and none of the exceptions of Art. 93 BGG were met.
Extracted reasoning
The ordered evidentiary supplements showed that the merits could not be decided without further proceedings, so immediate review would not save significant time or costs; a remand for further investigation does not ordinarily cause irreparable legal harm.
